Investigation of a combined platinum and electron lifetime control treatment for silicon

A Review of Platinum Diffusion in Silicon and Its Application for Lifetime Engineering in Power Devices

“…In very fast switching devices, a combination of different methods of lifetime control may thus be applied, i.e., irradiation techniques in addition to Pt diffusion. [4,13] As an illustrative example of the effect of lifetime adjustment with platinum, Figure 2 shows measurements of the reverserecovery transient current of a platinum-diffused diode and a diode without platinum. [14] The peak current is considerably smaller for the platinum-diffused diode.…”
